Creative DTT 2200 defective - help!!!

[amii]

HI

My creative (cambridge soundwork) DTT 2200 is playing dead. The light on the remote does not come on. The amplifier does not respond. I check the fuse and power supply both are OK.

There are not apparent bulky / leaky capacitor. I have tried to check the transistors (H945) and diodes but so far no luck.

I would welcome any suggestion /tips / schema to try to restore the amplifier

thanks
